This report presents the results of a survey of 2,799 students in Galway city and county. The students, from 40 secondary schools, were surveyed under strict supervision by self-administered anonymous questionnaire. The survey showed that 21% (574) of those surveyed have had sexual intercourse, mean age 15.45 years. Alcohol was a contributory factor in 35% of reported first sexualintercourse and drugs in only 9%. A total of 68% of respondents said that they always used condoms, with 24% using them sometimes and 8% never. Overall 68% reported drinking and 11% reportedusing drugs. Over 70% of respondents had received sex education and information on alcohol at school and 57% had received information on drugs at school. Preferred main source for both sexes of sex education, drug and alcohol information was school, followed by parents. The study concluded that despite a fairly good level of information, many teenagers are involved in risky behaviour.
